IMPROVEMENT IN lSHEET-METAL CANS.

Specification forming part of Letters Patent No. 81,692, dated Septemberl, 1868.

To all whom it may concern: v

Be itknown that I, CONRAD SEIMEL, of Green Point, in the county of Kingsand State of New York, have invented a new and useful Improvement in theConstruction of Sheet- Met-al Cans; and Ido hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the saine, referencebeing had to the accompanying drawingsdormin g part of thisspecification.

The invention relates to a new and useful improvementin the construction of sheet-metal cans.

The invention consists in a novel manner of forming or constructing thebody of the can as will be hereinafter more fully described.

In the accompanying sheet of drawings, Figure l is a transverse sectionof the body of a sheet-metal can constructed according to my invention.a: fr, Fig. 2, shows the line of section; Fig. 2, a side view of thesame.

Similar letters of reference indicate correspondin g parts.

The body of the can is composed of two pieces of metal, A A, bent eachin form so as to have the sides a a at right angles with each other, themetal at the angle of the sides a a being swaged or rolled so as to forma projection, b, of semi-cylin drical form, which extends the wholelength of the piece of metal. The ends of each 'piece of metal A arealso swaged or rolled to form a projection, c, similar to b.

The pieces of metal B are fitted together so that the projections c ofone piece of metal A may lap within or over the projections cof theother piece A, the two pieces A A forming va square body. When the twoparts or pieces I claim as new 'and desire to secure by Letters Patent-The square or rectangular sheet-metal can, constructed, as described, ofthe two pieces A A, bent to have the sides a a at right angles to eachother, and having formed at the angles the semi-cylindrical projectionsb, the ends of said parts a a being rolled to form projections c,lapping within and over each other, as herein described, for the purposespeciiied.
